It's best not to change lines that aren't related to the changes in the file. Makes it hard to go through the history of code later ("I wanted to see when this docstring was added -- why was it changed in this change??"). Can you revert the docstring/line wrapping changes?

We have a lot of variations in how we're creating this. Can you go through the change and make sure we always pull out diff = SimpleUploadedFile so it's explicitly done separately from the post operation?
